, p. 768 - 770 (1990)
Dialkyl (E)-2,3-dicyanobutendioates 4, potentially useful intermediates for the synthesis of a wide variety of heterocyclic compounds, are conveniently prepared by the reaction of alkyl bromocyanoacetates 2 with potassium thiocyanate in acetonitrile followed by treatment with water.The starting alkyl bromocyanoacetates are prepared by the photochemical reaction of the appropriate alkyl cyanoacetate with bromine in carbon tetrachloride.
